Patented Nov. 30, 1915.

' -.ZorzZZ-whom it may concern citizen of the United and State of .zBe it known-thatl, ROBERT G. Enmo'm', States, residing at South Bartonville, in the county of Peor a Illinois, have invented certam new and usefulImprovements in Mechani-- cal Movements; 'and'I do hereby declare that the following is 'a full; clear, and exact dethe operation of pumps,"

scription of the invention, which will'enable jothers skilled in the art to which it apperf tains-to make anduse the same.

3 his invention relates to a mechanical movement.

The movement is particularly adapted to a r, pumps or air compressors, and other mechanisms.

, --It relates particularly to an e'cc entrically mounted disk or wheel and ""ele'ment operated'by it the line of movement a reciprocating of-said element being inline with the'axis of rotation of saiddisk or" wheelbut pcrpen:

di'cular thereto.

The main object of the inventionri s' to provide a peculiarly constructed'mechanism,

Including an eccentric for imparting a re-. clprocatmg movement to an element, whereby reaction of stored energy through said movement 3 ittle ower-res element will be prevented fromrotating the latter.- A

Another object; is to provide a mechanical particularly adapted to air compumps and requiring but r'essors' or air:

the operation of said'compre'ssor or pump, the mechanisnri'ncluding means to prevent back 'companying drawing} "pressure reacting upon the power transmitting portion.

To the end that theinvention may be fully understood 1' have provided the adin which, Figurelis an elevation of my mechanical movement as'appliedto an air compressor.

Now, byrkeping the axisjof the piston rod of the compressor in line with the axis of D the back pressure can'have no efiect'whatever upon the wheel or disk in tending to rotate it in a contrary direction.
